Rapid analysis of fipronil and fipronil sulfone in eggs

Find here the complete workflow for rapid analysis of fipronil and fipronil sulfone in eggs from the sample to the result. For sample preparation a modified QuEChERS acetinitrile extraction protocol is described followed by LC-MS or GC-MS analysis delivering sensitive and reliable results.

Food analytical testing subtopics

Carbohydrates are important food components affecting taste and nutrition. The determination of the types and concentrations of carbohydrates in foods is integral for energy evaluation, nutritional labeling, quality control, and for identifying possible adulteration.

Nature provides the source for many dietary supplements. But there is still much to be learned about these molecularly diverse compounds. Our instruments and products allow customers to confidently extract, quality and identify these complex natural products.

Edible oils are among the most abundant cooking ingredients in the world. They are extracted from plants, seeds, nuts, and fruits. We understand edible oils present analytical challenges due to their chemical complexity.

Thermo Fisher Scientific has a strong commitment to supporting laboratories charged with the task of researching and monitoring environmental pollutants. Our commitment ensures high productivity, added value solutions for some of the most challenging environmental pollutant determinations.

Packaging and Food Contact Material compounds can migrate from polymeric materials used in food and beverage packaging into the foods and beverages themselves. Turn to us for solutions for the testing of these packaging chemicals in foods and beverage samples.

Processing contaminants are generated during the processing cycle of a product. They are formed when a chemical reaction takes place between the food and processing (e.g., disinfection, fermentation, heating, canning, or grilling).

Natural toxins are chemicals that are naturally produced by living organisms. They are of major concern to the worldwide economy because of annual revenue lost due to contamination, the toxicity to both animals and humans, and because they are persistent throughout multiple food processing steps.

The global nutraceutical industry is growing each year with the introduction of new products. For all nutraceuticals, the compositional quality and safety must be monitored to track contamination, adulteration, product consistency, and to ensure regulatory compliance.

Everything you need to ensure your success in pesticide analysis. That’s what we provide you and your laboratory. Start-to-finish workflows to help regulatory, food monitoring and testing laboratories meet the challenges of today and the future requirements of tomorrow in pesticide residue testing.

Trace elemental screening and speciation analysis is receiving global attention. Some elements are an essential part of a healthy diet, but others, such as lead, mercury, arsenic and cadmium, offer no nutritional benefits to humans and are actually toxic.

Antibiotics are a group of chemicals that are widely used in animal husbandry primarily for protection of animals from disease but also as growth promoters. The EU has set maximum residue limits for a variety of antibiotics in animal tissues, milk and eggs.
